Last year, The Chronicle obtained data on almost every property in the Bay Area — about 2.3 million unique records. We were hoping the data would be a treasure trove of information about real estate ownership in the region, allowing us to easily identify who owns what, and thus pinpoint the most powerful corporate owners of rental housing.

Quickly, we learned it wasn’t so simple. California doesn’t have hard-and-fast rules on how property owners identify themselves; large corporations, hedge funds and even wealthy families often purchase multiple homes through shell companies or trusts, shielding their names from ownership records. It’s only by carefully tracing networks of ownership that one can start to grasp how much property an entity actually has.

So we redoubled our efforts. During the past year, The Chronicle analyzed these property records, which were collected from county assessors’ offices, plus nearly 7 million unique business records. We used machine learning methods to parse the data and called on dozens of experts and additional data sources. This work yielded a list of 12 of the Bay Area’s largest, most influential ownership networks. We believe this is an unprecedented effort to uncover rental ownership and management networks across all nine counties in the region: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma…

We still aren’t sure we’ve captured all of the Bay Area’s largest owners, but we’re confident this list of 12 includes some of the region’s major power players in residential real estate, housing tens of thousands of families in nearly 7,000 assessor-defined properties from San Jose to Santa Rosa…

Even if the owner of your property isn’t on our list, you can learn more about who owns it by using our map of nearly 2.3 million Bay Area properties here. You may read more about our methodology here.

This tool will help you investigate your landlord or anyone else’s

To our knowledge, there has never been a centralized database where someone could see who owns any property in the nine-county Bay Area region, making it difficult to investigate connections between the powerful forces that shape the housing market for all. So The Chronicle built one.

Type in your full address, or any Bay Area address, to see who officially owns nearly any building. The map contains data on almost 2.3 million properties registered across the Bay Area’s nine counties, which The Chronicle obtained in summer 2021…(more)
